2015 GMC Sierra 1500 Other / unspecified Problems

I RECENTLY PURCHASED A GMC SIERRA 1500 FROM CARMAX FITTED WITH A SET OF CROSSCONTACT LX20'S. THE TRUCK HAD ABOUT 18,000 MILES OR FEWER WHEN I BOUGHT IT AND IT NOW HAS 31,000 MILES ON IT. THE TWO FRONT TIRES STARTED TO DISINTEGRATE AROUND 28,000 MILES AND NOW HAVE BECOME UNSAFE AND UNUSABLE. I CONTACTED YOUR CUSTOMER SUPPORT OFFICE AND WAS TOLD THAT THEY COULD NOT DO ANYTHING FOR ME AS I WAS THE SECOND OWNER AND I SHOULD CONTACT CARMAX. OF COURSE CARMAX SAYS, CALL CONTINENTAL. THE CODE ON ALL 4 OF MY TIRES IS A32A WBDE 2215. I HAVE ENCLOSED A FEW PHOTOS OF THE FRONT TIRES, THE BACK TIRES ARE SHOWING THE SAME SEPARATION FROM THE STEEL BELT, BUT NONE OF THE TREAD HAS COME OFF YET. I BELIEVE THE TURNING BACK AND FORTH OF THE FRONT TIRES HAS ACCELERATED THEIR DEMISE. I HAVE PURCHASED 4 NEW GOODYEAR TIRES BECAUSE I TRULY FEAR FOR MY FAMILIES SAFETY. I WOULD APPRECIATE YOUR TIME AND CONSIDERATION IN THIS MATTER.

BOUGHT SET OF FOUR DYNAPRO HT P255 70R17 TIRES. HAD TO TAKE THEM IN FOR RE-BALANCING THREE TIMES DUE TO ROUGH BUMPY RIDE. THIRD RE-BALANCING WAS TO A DIFFERENT DEALER THAN THE ORIGINAL SELLER. HE SAID TIRES WERE BADLY "OUT OF ROUND". ORIGINAL DEALER REPLACED TIRES WITH MICHELIN. HAD TO HAVE THESE TIRES 'ROAD FORCE BALANCED' AND PROBLEM WAS SOLVED.

MY TRUCK SUFFERS FROM VIBRATION PROBLEMS, THE SAME THING THAT 10,837 OTHER POSTS FROM OTHER PEOPLE SUFFERING THE SAME PROBLEM ARE TALKING ABOUT ON THIS FORUM. HTTP://WWW.GM-TRUCKS.COM/FORUMS/TOPIC/153186-SHAKE-OR-VIBRATION-ISSUES/PAGE-723 THIS FORUM HAS BEEN VIEWED OVER 1.5 MILLION TIMES WHICH MEANS A TON OF PEOPLE ARE HAVING THIS ISSUE. THIS IS ABSOLUTELY A RISK TO MOTOR VECHICLE SAFETY AND ABSOLUTELY EXISTS IN A GROUP OF VECHICLES OF THE SAME DESIGN OR MANUFACTURE. THE PROBLEMS THIS SHAKE PRESENTS THAT POSE A DANGER ARE VIBRATIONS SO SIGNIFICANT THAT IT CAN CAUSE DRIVER DISTRACTION, FATIGUE ON LONG TRIPS, POTENTIAL LOSS OF CONTROL, NOT TO MENTION LONG TERM HEALTH EFFECTS FROM VIBRATION EXPOSURE. THE HEALTH EFFECTS DEFINED ARE AS FOLLOWS: "THE EFFECTS OF WHOLE BODY VIBRATION (WBV) HAVE BEEN STUDIED EXTENSIVELY IN OCCUPATIONAL MEDICINE. IN PARTICULAR, IT HAS BEEN SHOWN THAT WHEN THE BODY UNDERGOES CHRONICALLY TO WHOLE BODY VIBRATIONS SPINAL DEGENERATION IS LIKELY TO BE ONE OF THE DELETERIOUS OUTCOMES. LOW BACK PAIN HAS BEEN SHOWN TO BE THE LEADING MAJOR CAUSE OF INDUSTRIAL DISABILITY IN THE POPULATION UNDER THE AGE OF 45 YEARS AND HAS BEEN LINKED TO WHOLE BODY VIBRATION EXPOSURE ENCOUNTERED IN SOME INDUSTRIAL SETTINGS. WHOLE BODY VIBRATION HAS BEEN RECENTLY PURPOSED AS AN EXERCISE INTERVENTION SUGGESTING ITS EFFECTIVENESS IN INCREASING FORCE-GENERATING CAPACITY IN LOWER LIMBS AND LOW BACK. IT HAS ALSO BEEN REPORTED TO BE AN EFFECTIVE NON-PHARMACOLOGICAL INTERVENTION FOR PATIENTS WITH LOW BACK PAIN. RELATIVELY SHORT EXPOSURE TO WHOLE BODY VIBRATION HAS BEEN ALSO SHOWN TO INCREASE THE SERUM LEVELS OF TESTOSTERONE AND GROWTH HORMONE. THE COMBINED EFFECTS ON THE NEUROMUSCULAR SYSTEM AND ENDOCRINE SYSTEM SEEM TO SUGGEST ITS EFFECTIVENESS AS A THERAPEUTIC APPROACH FOR SARCOPENIA AND POSSIBLY OSTEOPOROSIS."

THE GMC SIERRA HAS A TERRIBLE VIBRATION FROM 70 - 80 MPH. IT HAS BEEN IN THE SHOP 7 TIMES OVER THE LAST YEAR, 9 NEW TIRES, AND THE VIBRATION STILL CONTINUES. I HAVE ATTEMPTED TO RESOLVE THE ISSUE WITH GM BUT THERE HAS BEEN NO RESOLUTION. THE TRUCK FEELS UNSTABLE AND LIKE SOMETHING IS GOING TO BREAK ON THE HIGHWAY WHICH IS A SAFETY CONCERN. THIS VEHICLE HAS ISSUES AND IT NEEDS ADDRESSED.

I BOUGHT THE VEHICLE NEW IN 9/2015. I REPORTED A VIBRATION BETWEEN 75-80MPH TO THE NEARBY GM DEALER (TWICE). THE DEALER KEPT THE TRUCK FOR A FEW DAYS AND STATED THEY COULD NOT CORRECT THE PROBLEM. I TOOK THE TRUCK BACK TO THE ORIGINAL DEALER WHERE I BOUGHT IT, THEY DID A ROAD FORCE BALANCE ON THE TIRES AND REPORTED THE PROBLEM FIXED. I TOOK THE TRUCK BACK TO THE ORIGINAL DEALER AT 13K MILES, THEY KEPT THE TRUCK FOR A FEW DAYS AND REPORTED THE TIRES NEEDED TO BE REPLACED. THEY REPLACED THE TIRES AND STATED THE VIBRATION HAS BEEN RESOLVED. I DROVE THE TRUCK FOR ANOTHER 3K MILES AND NOTICED THAT THE VIBRATION WAS STARTING UP AGAIN. AT 18K MILES, I RETURNED THE TRUCK TO THE ORIGINAL DEALER AND THEY ARE GOING TO TRY AND RESOLVE THE PROBLEM A 5TH TIME.

WITHIN ONE YEAR OF PURCHASING THIS VEHICLE, AND OCCURRING NUMEROUS TIMES OVER THE COURSE OF 15,000 MILES, THIS VEHICLE SUDDENLY AND WITHOUT WARNING COMPLETELY LOST CONTROL IN WET CONDITIONS. VEHICLE WAS ALWAYS OPERATED WITH ALL SAFETY MECHANISMS INCLUDING TRACTION CONTROL ON. VEHICLE WAS ALWAYS OPERATED AT OR BELOW THE POSTED SPEED LIMITS AND WELL BELOW SPEED LIMITS IN WET CONDITIONS. ACCELERATING FROM A STOP AND TURNING ONTO ROADS EITHER FROM A STOP SIGN OR RED LIGHT, THE VEHICLE REPEATEDLY SPUN 90 TO 180 DEGREES FOR NO REASON. THE VEHICLE ALSO ON SEVERAL OCCASIONS COMPLETELY LOST CONTROL LATERALLY AND SLID SIDEWAYS AS IF ON ICE; SOMETIMES IN TRAFFIC AND FORTUNATELY NO DAMAGE OR INJURY OCCURRING. VEHICLE HAS BEEN TO THE DEALER WITH TIRES AND SUSPENSION FOUND TO BE WITHIN LIMITS. SINCE NO INDIVIDUAL COMPONENT WAS DEFECTIVE EITHER THE VEHICLE, TIRES, OR THE COMBINATION MUST BE INTRINSICALLY UNSAFE. GM CUSTOMER CARE WAS CONTACTED AND CASE [XXX] OPENED. GM WILL NOT PERFORM ANY ACTION OR REPLACE TIRES SINCE THEY CANNOT DUPLICATE THE LOSS OF CONTROL ON DRY ROADS. GM'S OFFICIAL RESPONSE TO ME WAS TO TAKE THE VEHICLE TO THE DEALER DURING A RAIN STORM AND WITH ONE OF THEIR TECHS IN THE VEHICLE, I WAS TO REPLICATE MY PROBLEM FOR THEM TO WITNESS. GM'S OFFICIAL RESPONSE TO ME, INCLUDING CUSTOMER CARE CONSULTANT AND DEALER SERVICE MANAGER WORKING THROUGH HIS DISTRICT MANAGER, WAS TO INTENTIONALLY MAKE THE VEHICLE LOSE CONTROL ON A PUBLIC ROAD. THIS SEEMS COMPLETELY IRRESPONSIBLE AND POTENTIALLY CRIMINALLY TO ME SHOULD ANY PROPERTY DAMAGE OR INJURY OCCUR AS A RESULT. I HAVE REPLACED THE TIRES AT MY OWN EXPENSE OF NEARLY $1000 ON A NEARLY NEW $50K+ TRUCK IN ORDER TO DRIVE SAFELY.
